Answer #1

A) C6H5OH   and C) N2H4 covalent compound

B) NiS   ionic compound

compound formed by metal and non metal is called ionic.

compound formed by only non metallic elements are called covalant compounds.

ionic compounds exisr as large crystals   by arranging somany molecule together form large crystal lattice. thats why we use empirical formulaa.   where as covalent compounds exist as single entities so we use molecular formula

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
